The synchronized keyword in JavaDeclaring a method as synchronizedTo the programmer, declaring a method as synchronized is essentially the same as wrapping the method body in a synchronized (this) block. So the above Counter class could be written: ...
Synchronization and concurrency before Java 5; Synchronization and concurrency in Java 5. Synchronization and lockingA key element of thread safety is locking access to shared data while it is being operated on by a thread. Perhaps the simplest— but not always the most versatile— way of ...
In this case, the thread acquires the intrinsic lock for the Class object associated with the class. Thus access to class's static fields is controlled by a lock that's distinct from the lock for any instance of the class. Synchronized Statements Another way to create synchronized code is ...
The Java interface for Mobile Sync client-side synchronization resides in the oracle.lite.msync package. The Java interface provides for the following functions: Setting client side user profiles containing data such as user name, password, and server Starting the synchronization process Tracking the...
事务同步管理器,管理每个线程的资源(对于事务,DataSource创建的连接对象connection等称作事务的资源)和事务同步(TransactionSynchronization---用来监听事务操作的回调类,其中定义了在事务执行过程中,进行的拓展操作,如before/after--commit/completion,在getSynchronizations中,对其进行sort排序返回)。
